STREET CAR MOTOR.

SPECIFICATION forming part of Letters Patent No. 397,658, dated February 12, 1889.

Application filed April 6, 1888. Renewed January 9, 1889. Serial No. 295,881. (No model.)

To all whom it may concern.-

Be it known that we, BURCHELL R. MOORE and CHARLEs D. M ONTANVE, of Kansas city, in the county of Vyandotte and State of K ansas, have invented a new and Improved Street-Car Motor, of which the following is a full, clear, and exact description.

The object-of the invention is to provide a new and improved motor specially adapted for propelling street-cars, and which is simple and durable in construction and very effective in operation.

The invention consists of certain parts and details and combinations of the same, as will be full described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional side elevation of a car provided with the improvement, and Fig. 2 is a sectional plan view of the same with parts of the floor broken out.

In the street-car A, of suitable size and shape, is located a gas-engine, B, of any proved construction, and provided with the usual piston-rod, C, connected with the crank D, formed on the main driving-shaft E of the engine. On the shaft E is also secured a second crank, F, standing at right angles to the crank I), and pivotally connected by the pitman G with the crank ll, secured to the shaft I, mounted to revolve in suitable bearings held on the bottom of the car A. 011 the shaft I is secured a second crank, J, standing at right angles to the crank H and pivotally connected by the pitman K to the outer proj ecting end of the piston-rod C of the gas-engine B. On the shaft I is also secured a friction-wheel, L, on the periphery of which is held a friction-pinion, N, also in contact with the friction-wheel O, secured to one of the axles P of the car A. The friction-pulley N is mounted. to rotate in the lower end of the arm Q, pivotally connected at its upper end to one end of the lever R, i'ulcrumed on the arm S, supported on the axle P. On the other end of the lever R is formed a handle, R, on which is pivoted the hand-lever T, having an arm, T, carrying a pin, T held to slide in a longitudinal slot, R formed in lever R. In the latter is also formed the vertical slot R in which is held the worm-wheel U, secured to the pin T above mentioned, and the said worm-wheel U is adapted to be thrown in and out of mesh with a vertical worm, V, secured to the floor of the car A.

The operation is as follows: hen the gasengine is set in motion and its main drivingshaft E is thereby revolved, then a similar motion is' imparted to the shaft I by the action of the cranks F, J, and H, the pistonrod 0, and the pitmen K and G. The friction-wheel L, secured on the shaft I, revolves with the latter and transmits its motion to the friction-wheel O by the friction-pinion N, held in frictional contact with both wheels L and 0. As the wheel 0 is secured to one of the axles of the car, the latter is propelled. When the operator desires to stop the car, he then takes hold of the handle R of the lever R and presses on the hand-lever T, so that the pin T carrying the worm-wheel U, slides outward and out of mesh with the worm V. The operatorthen moves the handle R downward, whereby the other end of the lever R is raised and with it the arm Q and frictionpinion N. The latter is thus thrown out of contact with both friction-wheels L and 0, so that the revolving motion of the wheel L is not transmitted to the wheel 0, and the forward movement of the car A is interrupted; but the engine B is permitted to run. \Vhen the operator desires to start the car, he moves the lever R to its former position, as shown in Fig. 1, so that the friction-pinion N is again thrown in frictional contact with both wheels L and O.

The arm S, which forms the fulcrum for the lever R, supporting the pinion N, is mounted on the axle P, so as to compensate for the lost motion when the car-wheels secured to this axle pass over rail-joints.

Having thus described our invention, what 9 we claim as new, and desire to secure by Letters Patent, is-

In a street-car motor, the combination,with the friction-wheel L, the means for rotating it, and the friction-wheel O on the car-axle, of

the pivoted lever R,havinga downwardly-exing' the said Worm U and extending through tending arm or link, Q, the friction-Wheel N a slot in the lever B, substantially as setforth. 10 on the lower end of said arm or link between 3 the Wheels L O, the vertical worm V near the outer end of the lever R, the sliding worm U 1 on said lever and meshing With the vertical \Vitnesses:
